Configuring Windchill
Changes must be made to your Windchill solution in the following locations:
wt.properties file
Modify wt.properties to include the address of the machine where Windchill Business Reporting is installed as a trusted host:
wt.auth.trustedHosts=<machine_ip_addr> <serverhost>
where <machine_ip_addr><serverhost> is the address of the machine where the Windchill Business Reporting is installed. In a distributed installation scenario, this is the machine where the Windchill Business Reporting host components are installed.
In HTTPSERVER_HOME/conf/conf.d create the file cognosreverseproxy.conf with the following contents:
<IfModule !proxy_http_module>
LoadModule proxy_http_module modules/mod_proxy_http.so
</IfModule>
ProxyPass /Cognos <cognos_url>
ProxyPassReverse /Cognos <cognos_url
where <cognos_url> is the fully qualified URL of the machine where the Windchill Business Reporting host components are installed. For example:
http://server1.mycompany.com/Cognos
PTC HTTP Serveradditions.conf
